Change Task Report Values?

Hi everyone,

Is possible change a Process Variable value, into a Task Report??

My Task Report is:

I want to change (with code, inside an interface, using functions or other things) the TaskAplication Text, for one record (first one for example). Changing "Aplicacion 6" to "Aplicacion 7".

I dont know if its possible, or the values of Process Variables Task are constants.

Thanks and regards!

Pablo.
